ALBERT-G. DUNDAS, OF AGRA, KANSAS..

CASHIER/S SHIELD;

"zi i i'eauoasiea February 13,1915; Serial No. i983."

;Beit known that I, ALBERT G. Doxoas, a citizen of the "United States, residing at Agra. in the county of Phillips and State of Kansas. have invented certaiirnew and useful Improvements in Cashiers- Shields, of which the following is a specification.

v invention relates to cashiers shields. and my object is to provide an apparatus of this character which can be readily installed at cashiers cages for protection against bnrgla rlv. I

The invention embraces means whereb a .cashier. on command of a burglar to hold up his hands, can mstantl close the door and windows of his cage and thus shut out the burglar and place him at a great disadvantage. J

The invention also embraces an alarm system whereby the immediate neighborhood and police l'ieatlquartcrs is instantly notified of the attempted burglary.

The invention is well adapted for use in banks and other commercial houses where the cashier's cage is more or less exposed to burglary, and .in order that said invention mav be well understood, reference will now be made to the accompanying drawings, in

which:

Figure l is a vertical section of a cashiers cage provided with my invention. Fig. 2 is an irregular horizontal. section on line 11-41. of Fig. 1. Fig. 3 is a diagram of an alarm circuit used in connection with the invention. Fig. is an irregular vertical section on line E ni of Fig. 1. Fig. 5 is a detail perspective of the shield and the customarv grille placed at the cashiers window. Fig. 6 isa detail plan view of a trigger' mechanism located at the door leading to the cage. Fig, 7, is a section on line VII-W ll of Figs, 6. Fl o' is a broken detail perspective ofa guidewav employed in carryingout the invention. Fig. {his a broken horizontal section of certain parts employed in carrying out. the invention.

A de lffitllGS the cashiers cage inclosed by the l alpartiticm l3 having ia door C. whereby the doorwa D leading into the case may be closed. The partition B may be at snrn shape as to best inclose the cage One ier s window E. provided with the grille F.,.-,T,he upper 30'ill()l} 0lf the partition B also has theusual side win- Specification of Letters Patent.

corner of the partition 13 contains the r mmed Mar; 14,1516.

dows G and H, whichmay be in'clos'edf either m glass or protected with grilles constructed of vertical rods I and J, respectively, to prevent a burglar from gaining-access tothe cage through said windows: v 6C 1 designates the shield constitutingan im portant feature of the present invention: Said shield is made,preferablyfi'of thin metal plate or other bullet; resisting material, and is mounted in vertical guideways 2, secured to the partition adjacent, "the windows E. G and H. i I l Normally the shield I is'held in lowered position with its upperedge approximately in line with the counter K,'b latches 3, engaging lugs 3 fixed to the "lower'portion of the shield. The latches 3 are fixedly-mounted upon rock-shafts l, 9 and l2. .The rockshaft elis journal'ed at one end iha guide way 2 and at its opposite end 'in bearing 5. Said rock-shaft 4 isprovided near as ends with fiXedly-mounted levers 6', carrying a treadle 7 at their free ends. Thet ieadl'e 7 extends approximately the length of the window G, and is normallyheld in raised position to hold its latch 3 in engagement with its respective lug'3 by coilsprings 8 embracing the rock-shaft l. i

The rock-shaft 9 is arranged below the window E and 'journaled in the two adjacent guideways 2. Said rock shaft Q'has a pair of fixedly-mounted levers 10 carrying a treadle 11 at their free ends. The rock'- s'naft is connected to the rock-shafts4 and 12. by arms 9*, so that said rock-shafts will operate in unison and release the latches from their respective lugs, when any oneof the 'treadles 7.,1-1 and 15, isd'epressed. The arms 9* are loosely connected in pairsflay links 9. each of which hasa pin andsl0t connection 9 with an adjacentjarin'ftl g to allow the outer ends of eaclrpair of arms to move toward each other as tlie' swfagdown ward with the'treadle 7."

The rocl -s11aft-12 is journalcd at-its ends in one of the guideways :2 and shearing-13, and like the roclc-shafts land9 is prdvided near its ends with a pair of'fixedly-inounted levers ll. carrying at their free endslt'he strong enough to sustain the weight of the treadles 7 11 and 15, I have shown auxiliary springs 16 and 17 applied to the rock-shafts 9 and 12 to assist said springs 8 in sustainingthe treadles 11 and 15, respectiyely.

In addition to providing means adjacent to the windows E, G, and H, for disengaging the latches 3, I have also provided means whereby said latches 3 may be released at a point distant from said windows In carrying out said means, I employ a pedal 18 which may be located at any point within the cage A, so. that the operator can release the latches 3 without going over to one of the treadles. One end of the pedal 18, is, preferably, arranged in a slot 19in the floor of the cage and has a cable 20 attached thereto. Said cable'20 runs around guide sheaves 21 and extends up through a hole 22 in the floor, and is attached to the treadle 7. Thus when the free end of the pedal 18 is depressed, it causes the cable 20 to pull downnpon the treadle 7 and release the latches 3 from the lugs 3*. The instant the latches 3 are released from the lugs 3, the shield 1 quickly rises and closes the windows E, G and H.

The raising of the shield 1 may be accomplished by counter-weights or other suitable means, but in the drawings, I have shown long coil springs '23 for this purpose. Said springs 23 are housed-in guideways-2. Their lower ends are secured to eyes 24 projecting from the lower portion of the shield, while their upper ends are connected to pins 25 secured to the upper ends of the guideways 2.

The upward movement of the shield 1 is stopped by two rods 26 extending from the fioor to the top of the window G, where they are bent outwardly as indicated at 27 to constitute abutments for the upper edge of the shield. Rods 26, in addition to acting as stops, constitute two terminals of an electric circuit in which the shield 1 acts as a switch to close said circuit when it contacts the bent portions 27 of rods 26. Said circuit may be embraced in any one of the well-known burglar alarm systems leading to police headquarters, and embodying a gong located either inside or outside of the bank or other building provided with my invention.

In Fig. 3, -I have shown a simple circuit comprising'the shield 1, the rods 26, a circuit wire 29, a gong 30, a source of electrical energy 31, and a switch 32. \Vhen the'shield 1 is released from the latches 3 and moves up into contact with the bent portions 27 of the rods 26, the circuit through the wire 29 is closed and sounds the gong 30, until either the shield '1 is lowered or the switch 32 is thrown opens As disclosed bv Figs. 1 and 4, the rods I and J at the windows G and H, respectively,

Figs. 1 and 6.

connecting the lower portions of said rods: .Howpy'er, if it IS inconvenient to dispense with said horizontal bar in the grille at the cashiers window E, I secure said grille to the shield 1. as disclosed by Fig. 5, so that it will rise with said shield and thus prevent the latter from being held down by a rod or other obstacle, interposed between said shield and the horizontal bar f of the grille F. 7

As the door C leading to the cage A is usually left open in warm weather to aid ventilation, it is desirable to have said door automatically close with the shield l without requiring the operator to walk over to said door for the purpose of closing the same. I accomplish this result by mounting a vertical shaft 33 adjacent the hinged side of the door in bearings 34, and providing the upper portion of said shaft with a fixedly-mounted collar 35, having a notch 36 for the reception of one end of a trigger 37, pivoted at 38 and having its free end 39 extending into the path of the shield 1, The lower portion of the shaft 33 is provided with a fixedly-mounted arm 40, the'free end of which bears against the door. A coil spring 41 embracing the shaft 33, rotates the same and causes the arm 38 to close the door C when the shield 1 rises and trips the trigger 35 out of the notch 36. The door 3' is provided with a spring lock 0, which locks the door in closed position. The door is further locked by the free end of the arm 40 entering a notch c-- ios be understood that should a burglar enter the room containing the cage A-"with the intention of holding up the cashier, the latter can insta'ntlyprotect himself by closing -the door and the windows of said cage on pressing downward upon any one of the treadles or the pedal, .while standing or sitting with his hands raised above his head and without danger of divining his purpose to the burglar. It is also evident that when thus hidden from the burglar the cashier will have full command of the situation and if hebe armed, can bring said burglar down by firing through port-holes which may be provided inthe lower portion of the partition.

\Vhile I have shown and described the preferred form of my invention. I reserve the right to make such changes in the construction. combination and arrangement of parts as properly fall within the spirit and scope of the appended claims.

Having thus described my invention, what I claimand desire to secure by Letters Patent,- is:

1. In combination with a partition having a window therein, a grille at said window to normally close the same, a shield for closing said window and to which the grille is secured, so that the latter will be moved away from the window when the former closes said window, means to normally hold said shield open, and resilient means for closing said shield when it is released from the first-mentioned means,

2. In combination with a cashiers cage having one or morev'windows, a shield for closing said windows and constituting an electric switch, means to hold said shield open, means to close said shield and an alarm circuit embodying two terminals arranged in the.path of said shield so that the latter may close said circuit when closing the windows.

In combinationwith a cashiers cage having one or more'windows, a shield for closing said windows, and constituting an electric switch, means to hold said shield open, rods to check' the movement of said shield after the same has closed and act as electric conductors, means to close said shield, and a normally open alarm circuit connected to said rods, for the purpose described. Y
